Having the best of both worlds: naming performances of neurotypical individuals through AI-Generated images

Background Word retrieval deficits are one of the hallmark symptoms of people with aphasia (PWA). Psycholinguistic variables can predict word retrieval accuracy and latency in aphasia, but results to date have been mixed. Aims In this study, we investigate the effects of age of acquisition (AOA), familiarity, word frequency, and word length on the naming accuracy and reaction time of Persian-speaking PWA. Methods & Procedures This study consists of 25 participants with mild to moderate aphasia who completed a confrontation naming test. Naming accuracy was determined per participant per picture and reaction times were calculated using DMDX and CHECKVOCAL. Outcomes & Results The results showed that the four psycholinguistic variables were significantly correlated with naming accuracy and reaction time across the group of PWA. Multiple linear regressions demonstrated that among the four psycholinguistic variables, word familiarity had the strongest effect on reaction time; frequency and familiarity were most predictive of naming accuracy. Conclusions The purpose of the present study was to evaluate the influence of four psycholinguistic variables on word retrieval in Persian-speaking PWA using picture naming. The result of this study showed that word familiarity led to more accurate and faster retrieval, while word frequency led to more accurate word retrieval. The effect of psycholinguistic variables in picture naming is relevant to various fields of study, such as the underlying processes of language production, brain lesions, and functional imaging of naming.

Objective. This study aims to determine the extent to which psycholinguistic variables are included in the analysis of the quality of directive posters on social media during Covid-19. Methods. The methods used in the study include analysis of the relevant scientific literature on the identification of psycholinguistic categories and variables relevant to the study; expert assessment of qualitative parameters of posters published on Facebook by official organizations; methods of descriptive statistics. Results. The analysis of 298 unique works conducted through Ukrainian network on Facebook revealed that the overall average quality of the publications is on the borderline between medium and high levels – 69.3% (by text parameters – 70.0%, graphic parameters – 68.6%). Conclusions. The study revealed that psycholinguistic variables such as readability, imageability, concreteness, conceptual familiarity, semantic size, name agreement, image agreement, visual complexity, typicality, image variability, authenticity of texts, processing fluency, etc. penetrate deeply related research on the creolized texts in various forms and interpretations. The quality of the posters on Facebook made by the official institutions operating in the field of health care is at the borderline between medium and high levels. These indicators are most in need of improvement on text parameters such as “Emphasis” and “Call to action”, as well as on graphical parameters such as “Presence of interactive graphic links” and “Understandability of illustration message without text”.

Introduction The ability to name pictures has been investigated widely in healthy people and clinical populations. The Object and Action Naming Battery (OANB) is widely used for psycholinguistic research, aphasia research, and clinical practice. Normative databases for pictorial stimuli have been conducted in language processing studies to control for various psycholinguistic variables known to affect the availability of picture names. The present study provides Moroccan Arabic norms for name agreement, familiarity, imageability, visual complexity, and age of acquisition for 100 line drawings of actions and 162 line drawings of objects taken from Druks and Masterson. Methods and procedures 160 healthy Moroccan Arabic-speaking individuals participated in this study. Name agreement values for the OANB items were collected from forty subjects, followed by collecting data for the psycholinguistic variables: spoken-word frequency, imageability, visual complexity, and age of acquisition from 120 participants. Results The Moroccan Arabic OANB (MA-OANB) comprises 70 objects and 60 action pictures. 77% of the nouns and 68% of the verbs obtained 100% target responses. A minimum of 93 percent name agreement was reached for the remaining items. Norms were also collected for the following psycholinguistic variables: spoken-word frequency, imageability, age of acquisition, and visual complexity. Conclusion The stimuli can be used for various psycholinguistic investigations and also for assessment and therapeutic purposes in Morocco.

Naming accuracy for nouns and verbs in aphasia can vary across different elicitation contexts, for example, simple picture naming, composite picture description, narratives, and conversation. For some people with aphasia, naming may be more accurate to simple pictures as opposed to naming in spontaneous, connected speech; for others, the opposite pattern may be evident. These differences have, in some instances, been related to word class (for example, noun or verb) as well as aphasia subtype. Given that the aim of picture-naming therapies is to improve word-finding in general, these differences in naming accuracy across contexts may have important implications for the potential functional benefits of picture-naming therapies. This study aimed to explore single-word therapy for both nouns and verbs, and to answer the following questions. (1) To what extent does an increase in naming accuracy after picture-naming therapy (for both nouns and verbs) predict accurate naming of the same items in less constrained spontaneous connected speech tasks such as composite picture description and retelling of a narrative? (2) Does the word class targeted in therapy (verb or noun) dictate whether there is 'carry-over' of the therapy item to connected speech tasks? (3) Does the speed at which the picture is named after therapy predict whether it will also be used appropriately in connected speech tasks? Seven participants with aphasia of varying degrees of severity and subtype took part in ten therapy sessions over five weeks. A set of potentially useful items was collected from control participant accounts of the Cookie Theft Picture Description and the Cinderella Story from the Quantitative Production Analysis. Twenty-four of these words (twelve verbs and twelve nouns) were collated for each participant, on the basis that they had failed to name them in either simple picture naming or connected speech tasks (picture-supported narrative and unsupported retelling of a narrative). These were placed in a larger cohort of verb and noun sets for therapy. Post-therapy assessments examined naming accuracy and speed of target items in single-word picture-naming and naming accuracy in connected speech contexts. There was a step-wise decrement in naming accuracy over the three naming contexts following targeted therapy. Simple pictures elicited the most correct names, followed by picture-supported narratives and lastly unsupported narratives. Picture-naming accuracy significantly predicted naming in the connected speech contexts for the group as a whole. The speed of picture naming after therapy did not predict the extent to which items were named in composite picture description and narrative tasks. The findings suggest that gains in naming accuracy obtained through picture-naming therapy may generalize to naming of the same items in more linguistically and cognitively demanding connected speech tasks. Demonstrating this generalization is methodologically challenging and the method utilized in this study may serve as one starting point for gathering a larger database in order to answer the question posed by this paper more robustly.

Background Speech intelligibility is the degree to which the speaker’s intended message is recovered by the listener. There are several measures available for speech intelligibility assessment. Multiple studies have examined speech intelligibility assessments across different languages and populations. However, there remains a lack of specific speech intelligibility tests for Indian languages. The present study aims at the development of test stimuli and content validation of language-free word stimuli to assess speech intelligibility. Method The study was conducted in four phases which includes the following: enumerating consonants available in the Dravidian language family and content validation; development and content validation of language-free word stimuli to assess speech intelligibility; content validation of audio-recorded language-free word stimuli, and development and content validation of rating scale and administration of test stimuli in neurotypical individuals . Results Initially, a total of 17,756 words using combination generation in Excel, which was narrowed down to 4000 trisyllabic words with the vowel /a/. Further refinement resulted in 348 trisyllabic words based on the frequency of phonemes in Dravidian languages, considering all consonant positions. Content validation was conducted using the Delphi technique. The final selection of trisyllabic words was based on the content validation ratio (CVR) and content validation index (CVI) scores, resulting in 119 relevant words. The recording of those words was carried out by four speakers (two male and two female). Those recordings were validated by two speech-language pathologists using a ranking system. Based on the ranking, the investigator selected a male speaker who had the best clarity as a source of recording. The investigator administered the prerecorded trisyllabic word stimulus to the participants (30 neurotypical individuals; the age range of 19–65 years) bilaterally. The investigator asked the participant to repeat those words, whatever they heard through the headphones, and those responses were transcribed and analysed by the primary investigator. Out of a total of 119 words, 45 were eliminated from the list because they were (neurotypical individuals) produced incorrectly. The final word list contains 74 trisyllabic words. Conclusion The language-free stimuli can be used for the speech intelligibility assessment of native Dravidian language speakers with dysarthria, neurological conditions like Parkinson’s disease, bulbar palsy, post-glossectomy patients, etc. Future studies can focus on the clinical validation of the stimuli among disorder populations such as dysarthria.

Chronic communication impairment is common after stroke, and conventional speech and language therapy (SLT) strategies have limited effectiveness in post-stroke aphasia. Neurorehabilitation with non-invasive brain stimulation techniques (NIBS)—particularly repetitive transcranial magnetic stimulation (rTMS) or transcranial direct current stimulation (tDCS)—may enhance the effects of SLT in selected patients. Applying inhibitory NIBS to specific homologous language regions may induce neural reorganization and reduce interhemispheric competition. This mini review highlights randomized controlled trials (RCTs) and randomized cross-over trials using low-frequency rTMS or cathodal tDCS over the non-lesioned non-language dominant hemisphere and performs an exploratory meta-analysis of those trials considered combinable. Using a random-effects model, a meta-analysis of nine eligible trials involving 215 participants showed a significant mean effect size of 0.51 (95% CI = 0.24–0.79) for the main outcome “accuracy of naming” in language assessment. No heterogeneity was observed (I2 = 0%). More multicenter RCTs with larger populations and homogenous intervention protocols are required to confirm these and the longer-term effects.

Current research investigating collaboration between parents and speech and language therapists (SLTs) indicates that the SLT role is characterized by therapist-led practice. Co-working with parents of children with speech and language difficulties is less frequently described. In order to embrace co-working during intervention, the SLT role may need to be reframed, focusing on acquiring skills in the role of coach as well as the role of planning intervention and treating children. To report (1) SLTs' conceptions about their own roles during intervention for pre-school children with speech and language difficulties; and (2) SLTs' conceptions of parents' roles during intervention. A qualitative study used individual, semi-structured interviews with 12 SLTs working with pre-school children. Open-ended questions investigated SLTs' expectation of parents, experience of working with families, and the SLTs' conception of their roles during assessment, intervention and decision-making. Thematic network analysis was used to identify basic, organizational and global themes. SLTs had three conceptions about their own role during intervention: treating, planning and coaching. The roles of treating and planning were clearly formulated, but the conception of their role as coach was more implicit in their discourse. SLTs' conception of parents' roles focused on parents as implementers of activities and only occasionally as change agents. Collaboration that reflects co-working may necessitate changes in the conception about the role for both SLTs and parents. SLTs and parents may need to negotiate roles, with parents assuming learner and adaptor roles and SLTs adopting a coaching role to activate greater involvement of parents. Applying conceptual change theory offers new possibilities for understanding and enabling changes in SLTs' conception of roles, potentially initiating a deeper understanding of how to achieve co-working during speech and language intervention.

Research into lexical retrieval requires pictorial stimuli standardised for key psycholinguistic variables. Such databases exist in a number of languages but not in Arabic. In addition there are few studies of the effects of psycholinguistic and morpho-syntactic variables on Arabic lexical retrieval. The current study identified a set of culturally and linguistically appropriate concept labels, and corresponding photographic representations for Levantine Arabic. The set included masculine and feminine nouns, nouns from both types of plural formation (sound and broken), and both rational and irrational nouns. Levantine Arabic speakers provided norms for visual complexity, imageability, age of acquisition, naming latency and name agreement. This delivered a normative database for a set of 186 Arabic nouns. The effects of the morpho-syntactic and the psycholinguistic variables on lexical retrieval were explored using the database. Imageability and age of acquisition were the only significant determinants of successful lexical retrieval in Arabic. None of the other variables, including all the linguistic variables, had any effect on production time. The normative database is available for the use of clinicians and researchers in the Arab world in the domains of speech and language pathology, neurolinguistics and psycholinguistics. The database and the photographic representations will be soon available for free download from the first author's personal webpage or via email.

This paper presents a new corpus of 140 high quality colour images belonging to 14 subcategories and covering a range of naming difficulty. One hundred and six Spanish speakers named the items and provided data for several psycholinguistic variables: age of acquisition, familiarity, manipulability, name agreement, typicality and visual complexity. Furthermore, we also present lexical frequency data derived internet search hits. Apart from the large number of variables evaluated, these stimuli present an important advantage with respect to other comparable image corpora in so far as naming performance in healthy individuals is less prone to ceiling effect problems. Reliability and validity indexes showed that our items display similar psycholinguistic characteristics to those of other corpora. In sum, this set of ecologically valid stimuli provides a useful tool for scientists engaged in cognitive and neuroscience-based research.

BACKGROUND: Waiting lists for speech and language therapy exist when services do not meet demand. Waiting lists pose practical and ethical challenges for speech and language therapists (SLTs) and workplaces to manage, with potential flow on effects for children and families. OBJECTIVE: The present study aimed to describe SLTs’ perspectives about waiting lists for children with speech, language, and communication needs (SLCN) and explore waiting list management strategies. METHODS: The present study reports on 187 SLTs’ written responses to open-ended questions in a questionnaire. SLTs were from nine countries, had an average of 12 years’ experience in the profession (range 0.2–45 years), and either currently or had previously worked with children. Data were analysed qualitatively using thematic analysis. RESULTS: SLTs’ feelings about their waiting lists centred on three themes: (1) negative (e.g., “overwhelmed”, “stressed”, “anxious”, “embarrassed”); (2) neutral (e.g., “not too bad”, “okay”); and (3) positive (e.g., “manageable”, “proud”). Four themes related to waiting list management: (1) SLT service delivery (e.g., triage, use of technology in service provision); (2) workplace processes and policies (e.g., eligibility criteria, prioritisation); (3) SLT workforce (e.g., recruitment and retention of skilled SLTs); and (4) inaction (e.g., waiting list management was “out of my hands”). CONCLUSIONS: Waiting lists can have negative consequences and many SLTs take action to manage waiting lists; however, waiting list management strategies are not necessarily effective which can impact children’s outcomes. There is a need to reimagine service delivery and identify effective actions for managing speech and language therapy waiting lists at a local and systemic level in order to optimise outcomes for children and families.

In recent years, a considerable number of studies have tried to establish which characteristics of objects and their names predict the responses of patients with Alzheimer's disease (AD) in the picture-naming task. The frequency of use of words and their age of acquisition (AoA) have been implicated as two of the most influential variables, with naming being best preserved for objects with high-frequency, early-acquired names. The present study takes a fresh look at the predictors of naming success in Spanish and English AD patients using a range of measures of word frequency and AoA along with visual complexity, imageability, and word length as predictors. Analyses using generalized linear mixed modelling found that naming accuracy was better predicted by AoA ratings taken from older adults than conventional ratings from young adults. Older frequency measures based on written language samples predicted accuracy better than more modern measures based on the frequencies of words in film subtitles. Replacing adult frequency with an estimate of cumulative (lifespan) frequency did not reduce the impact of AoA. Semantic error rates were predicted by both written word frequency and senior AoA while null response errors were only predicted by frequency. Visual complexity, imageability, and word length did not predict naming accuracy or errors.

Are the effects of tDCS in language rehabilitation in primary progressive aphasia specific to the task trained?

A common early intervention approach for preschool children with language problems is parent–child interaction therapy (PCIT). PCIT has positive effects for children with expressive language problems. It appears that speech and language therapists (SLTs) conduct this therapy in many different ways. This might be because of the variety of approaches available, the diverse set of families SLTs work with or the different organizational structures. Understanding the critical components of PCIT would enable SLTs to map the variations that are implemented and researchers to evaluate the effects of such variation. This study aimed to identify the potentially critical components of PCIT based on the practical experience of SLTs and to identify SLTs’ rationales for the way they structure PCIT. Both parameters are important for the long term goal, that is, to develop a framework that can be used to support practice. Semi-structured interviews were conducted with 10 SLTs who had at least one year experience in delivering PCIT with preschool children with language impairment. The interviews were transcribed and analysed, using thematic analysis. Analysis of the SLT interview data identified four potentially critical components that underpin the teaching of strategies to parents: parents’ engagement, parents’ understanding, parents’ reflection and therapists’ skills. SLTs suggested that all four components are needed for the successful delivery of PCIT. The reasons that SLTs give for the way in which they structure PCIT are mainly based on organizational constraints, family needs and practicalities. SLTs consider PCIT to be valuable but challenging to implement. A framework that makes explicit these components may be beneficial to support practice.

Aphasia commonly leads to word retrieval issues, particularly with nouns and verbs. Traditional assessments often focus on single-word. This study uses qualitative and quantitative methods to assess word class deficits in Kannada-speaking Individuals with Aphasia (IWA) compared to Neurotypical Individuals (NTI) in single-word production and discourse production. Twenty IWAs (aged 20-50) and twenty age/gender-matched NTIs were recruited. Confrontation naming evaluated single-word production, while structured picture description (picnic scene) assessed discourse. Both tasks included a fixed set of nouns and verbs for comparison. The results were that IWAs performed poorer than NTIs in both tasks. Statistically significant noun and verb usage differences were observed between IWAs and NTIs in the picture description task (p<0.05). However, word class differences in the IWA group were insignificant across tasks. NTIs showed significant differences only in the picture description task. This study underscores word class deficits in aphasia, particularly at the discourse level. Discourse analysis is crucial for understanding language characteristics in aphasia and should be integrated into routine assessments.

The double burden of malnutrition and diet-related disease has been attributed to diets high in ultra-processed and discretionary foods, with increased sugars, saturated fats, and sodium, and insufficient dietary fibre. There is a limited understanding of the role of other macronutrients and micronutrients. Determine the highest priority nutrients to address both malnutrition and diet-related disease in Australia and New Zealand, for each demographic group and the total population. A novel four-step methodological approach was undertaken to identify: 1. Demographic (age-sex) groups; 2. Health priorities; 3. Potential nutrients based on inadequacy, increased requirements, and health priority association; and 4. Priority nutrients. Nutrient intake data was obtained from the most recent Australian and New Zealand nutrition surveys. Health priorities were based on national statistical data and expert consultation. High-level scientific literature (systematic reviews) was scoped for associations with health priorities and the suitability of recommended intakes. A quantitative scoring matrix was developed and used to determine the highest priority nutrients, with scoring over three domains: extent of inadequacy; consensus for increased requirements; and degree of association with health priorities. Nutritional inadequacies were common, with 22 of 31 essential nutrients consumed below recommended levels. Nine priority nutrients were identified across the demographic groups, with each demographic group characterised by a specific subset of these. Six nutrients were highest priority within the total population: vitamin D, calcium, omega-3 fatty acids, magnesium, folate, dietary fibre. The extent of nutritional inadequacies in Australia and New Zealand is high, both within each demographic group and the entire population, relative to both recommended intakes and key health outcomes. The methodology can be applied to other countries and globally. Findings make a significant contribution to understanding the nutrients to prioritise in future-proofing the health of the Australian and New Zealand populations. Guidelines and policies can target priority nutrients to address the malnutrition and diet-related disease double burden.
